    If you use a heat exchanger to warm incoming air with outgoing air, it should be possible to recover and reuse the moisture.

    No, an MHD generator won't work for neutrons, since neutrons don't interact with the electromagnetic force. However, you could use Project Orion design for a starship. There's an additional benefit: Project Orion is doable with today's technology (well, 60's technology to be exact), without requiring any breakthroughs such as controlled fusion reactors.

    The by-product of the reaction that generates the energy is the issue here. Efficiency losses on energy conversion has nothing to do with the reactions by-products impact on the makeup of the atmosphere.

    Of course they do. Conversion losses mean that you need to burn more fuel to get the same amount of energy, which produces more by-products, which makes the impact bigger.

    For a practical example, see this graph about steam engine efficiency: if you need to produce a megajoule of energy, a modern steam engine needs just a tiny fraction of coal to produce it than the first steam engines did, and thus also produces just a tiny fraction of CO2 as a byproduct.

    The economy will never be "post-scacity", as there's only so much shoreline property. There will always be desireable stuff that is scarce, and there will always be stuff that is desireable it's scarce - even if it's just the concert T-shirt that shows you listened to that band before it was cool.

    However, there is a huge qualitative difference between an economy where food and other basic necessities are scarce, and an economy where collectible t-shirts are scarce: in the former you either be a cog in the system or die, while in the latter you are free to live pretty much as you please. In fact the latter could certainly be called a post-scarcity economy, since all the things that are scarce are in the "might be nice to have" -category.

    Maybe its just me, but your logic of using an illegal situation to justify why a digital economy shouldn't exist seems like a bad argument.

    It's not. What keeps the government or any other organization in check is that there are ways around its power. Making the government actually capable of monitoring the small person-to-person transactions is asking for trouble. A society that's actually capable of enforcing all its laws is just a truly horrendous tyranny waiting to happen, and probably won't have to wait for long.

  15. Re:Keep it up. on Linux 3.3 Released · · Score: 1

    The firefox guys should've kept their versions at c.y instead of dropping the constant c, and everyone would've been happy. A number that changes scares people - but prefix it with a number that doesn't change and people are ok with it.

    More to the point, c+1.y is supposed to indicate that the release has major new features compared to c.*, while c.y+1 means some bug(s) in c.y have been fixed.

    Firefox changed this scheme partially for marketing reasons, but mostly to remove the ability for users to stay on a particular c series. In other words, you can't get bugfixes without new features, which inevitable end up introducing new bugs. No, you have to act as beta tester for whatever the Firefox team comes up with. At the same time, if the Firefox team decides you don't need no stinking status bar, you will either give up either it or bug fixes. To put it even blunter, Firefox versioning scheme changed so that users would have less choice, and would have harder time forming a critical mass at any particular "feature level" to make a branch.

    That's why people hate the new Firefox versioning scheme: it's a deliberate attempt to make them as powerless as possible in an open-source project. Which is understandable from a developer point of view, since backporting bugfixes into old branches is a waste of resources. And of course every designer wants their pet feature be used by everyone, so succumbing to the temptation of forcing the issue is quite understandable.

    I dunno about the "half the people" part, but the part about secred deals being against public interest is simple logic: if the rumours were worse than the truth, the politician would simply leak the deal - it's in his best interests to look as good as possible, after all. Thus, as long as the deal remains unknown, we know for certain that the people who know it consider it worse than whatever speculation we engage in here.

    Because people often have an adverse emotional reaction to a herd of photographers persuing them.

    The thing is, a "herd of photographers" is an annoyance, just like, say, a herd of mosquitos would be. Now, everyone would rather avoid a herd of mosquitos; but if you do so in a manner that obviously endangers yourself and others, and it ends badly, the fault lies with you, not the mosquitos, no matter how disgusting their bloodsucking parasitic nature might be.

    I hate to use the term "personal responsibility", since it's been corrupted into a form of Just World Fallacy by right-wing bandits, but nothing else really fits here: just because you have an "adverse emotional reaction" doesn't mean that a stupid decision made by you wasn't really made by you. It just means that the rest of us might take it into account and be more lenient or sympathetic than we otherwise might be (see various heat-of-passion laws). Luckily, that doesn't apply here, since the people making those stupid, recless and frankly extremely selfish decisions ended up killing themselves rather than some innocent bystander.

    In other words, adults are expected to put up with some amount of "adverse emotional reaction" without acting crazy.

    The fact is the paparazzi pursuing was a factor.

    Simply because someone selling you a faulty alarm clock directly resulted in you waking late the next morning doesn't mean that they are a factor in you speeding on your way to work, at least not in the "partially responsible for" sense.

  20. Re:Scientists or politicians on Neutrinos Travel No Faster Than Light, Says ICARUS · · Score: 3, Insightful

    Give you an example: evolution. Religious faith in science says "Evolution is proven. Anyone who believes otherwise is batty." A more scientific viewpoint of it would look at the progression of evolution theory, and see that evolution is simply a pretty good theory that definitely has needed refinement, and almost as definitely will still need refinement.

    You picked a bad example. With everything from breeding dogs to bacteria developing immunity to various drugs to fossil record speaks in favour of evolution, I have a very hard time to believe that any arguments against are done in good faith.

    A person with that second viewpoint will look at creationists' arguments against it -- and they do have some good ones -- not as being batty, but actually as pushing the theory to account for holes that still exist.

    Creationists aren't making scientific attacks against any particular evolutionary theory, they believe that the Genesis is a literal depiction of events and that evolution - specifically, the concept that humans evolved - conflicts with this (ironically, a literal reading of Genesis would actually require evolution to happen afterwards to get from two humans to current multiple ethnicities), so they come up with (usually batshit insane) attacks against it (and science in general, since studying the world will pretty much inevitably lead to the concept of evolution), with the whole Intelligent Design thing being the latest.

    Let me assure you: it isn't that the creationists are wacko. It is that they've really found a flaw in the theory.

    Yes, they are. Specifically, they are starting with an unassailable preconception of reality - namely, that the Genesis is a literal depiction of events that took place 4000-10000 years ago - and fit all evidence into this framework. This, of course, results in an extremely twisted worldview. And the "flaw" in evolution is that it conflicts rather seriously with creationism.

    None of this means that creationism is false, BTW; in other words, none of this proves that the world wasn't created 4000-10000 years ago (or last Thursday, for that matter). It's just that no one would look at all the available evidence and come to that conclusion without having an unassailable (by evidence) belief in it beforehand.

    In other words, "creationism" is what happens when confirmation bias meets bad theology and crusader mentality.

    I'm not familiar enough with other garbage collected languages and such workloads to know if this is inherent or just a problem with the Python GC.

    It's inherent. I noticed the exact same effect on Java programs I wrote: once the program starts using swap, garbage collection takes forever. I believe that the problem is because a garbage collector has to, in the worst case, hit every page of the working set to trace live objects, possibly several times (meaning that the page can potentially be swapped in and out several times per collection).
